INVENTOR JESSE L. NUBLA SMOKE FILTERING DEVICE This invention relates toa smoke filtering device for use with various smoking articles such ascigars, cigarettes, and the like. More particularly, this inventionrelates to a smoke filtering device which includes a plurality offilters of different types.

BACKGROUND AND OBJECTS The prior art has taught many types of devicesfor use with smoking tobacco for the purpose of filtering the smokeassociated therewith. These devices have included the quite commonfilters integral with the cigarette, and have also included devices towhich the cigarette is attached. This latter type of device may includea filter in the mouth piece, or route the smoke through a series offilters.

However, these devices have had associated therewith numerous drawbackssuch as the necessity for frequent changing of the filter, or refillingof the liquid if a liquid filter is used.

Therefore, a primary object of this invention is to overcome thedifficulties associated with prior art smoking devices.

Still another object of this invention is to provide a smoke filteringdevice which includes a plurality of filters.

Yet another object of this invention is to provide a smoke filteringdevice which includes different types of filters.

Still a further object of this invention is to provide a smoke filteringdevice which includes a combination of a liquid and porous filters.

, Yet a further object of this invention is to provide a smoke filteringdevice which includes a liquid filter having a perfumed liquid therein.

Yet another object of this invention is to provide a smoke filteringdevice utilizing a small, two part receptacle.

These and other objects and advantages of this invention will becomeapparent when considered in light of the following description andclaims when taken together with the accompanying drawings in which:

FIG. 1 is a sectional view of the smoke filtering device of thisinvention;

FIG. 2 is a left end view of the device of FIG. 1;

FIG. 3 is a top plan view of the device shown in FIG. 1.

DESCRIPTION OF THE INVENTION Referring now to FIG. 1, a receptaclegenerally designated is shown as having a top portion 12 and a bottomportion 14. The top portion 12 and bottom portion 14 are connected by afriction fit as indicated at 16. This connection should be fluid tightto prevent drawing air therethrough or spilling of liquid therefrom.

Passing through the top portion 12 is an L-shaped inlet member 18 havinga depending portion 20 which extends toward the bottom of portion 14 andterminates short thereof. Positioned within portion 20 of inlet 18 is aporous filter 22 which is retained in portion 20 by a friction fit.

The bottom portion 14 of the receptacle 10 has therein a liquid 24. Theportion 20 of inlet 18 extends below the surface of liquid 24 so thatsmoke passing through the inlet 18 is bubbled through the liquid 24.Liquid 24 may be of any suitable composition such as water or the like,and serves to filter and cool the smoke passing therethrough.Additionally, liquid 24 may include a perfuming substance which willimpart a pleasing aroma to the smoke passing therethrough.

Positioned within the top portion 12 of the receptacle l0, andsubstantially filling the top portion 12, is an additional porous filtermedium 26. This filter may be of the same material as that of filter 22,or it may be different.

Extending from the upper surface of the top portion 12 and at an acuteangle thereto is an outlet 28 having a mouth piece 30 secured thereto.The mouth piece 30 is of the usual construction as to enable acomfortable fit in the mouth of the user. Within the outlet 28 isanother porous filter 32. This filter 32 may be of the same material asthat of filters 22 and 26 or may be different therefrom.

In use, a cigarette or other smoking article C is held in inlet 18 by africtional engagement therewith. The user places the mouth piece 30 inhis mouth, and by drawing through the mouth piece in the usual manner,the smoke from the cigarette C passes through the inlet 18 to the filter22. This provides a preliminary filtering of the smoke.

Next, the smoke passes through the liquid filter 24 where it is cooled,and if desired, is perfumed. The smoke bubbles out of the liquid 24 andpasses next through filter 26. Finally, the smoke passes through filter32 and mouth piece 30 into the mouth of the user.

The filters 22, 26 and 32 may beeither a foam type, a ceramic type, or afibrous type of filter, and their porosity and filtering capabilitiescould be made to suit the wishes of the user. Suitable filter materialswould include cellulosic fibers, synthetic resin foams such aspolyurethanes or polystyrenes, of any of the conventional porousceramics.

It should be noted that the filtering device of this invention could bemade quite small, approximately the size of a pack of cigarettes, and insuch a manner as to be carried about by the user without theincumberances normally associated with prior art types of filters.

Furthermore, this invention provides the advantage that by utilizing theplurality of filters, the filters would not need to be changed asfrequently as a number of prior art types.

By utilizing this invention, one would still gain the satisfaction ofsmoking, but with substantially reduced health hazards.

While this invention has been described, it will be understood that itis capable of further modification, and this application is intended tocover any variations, uses and/or adaptations of the invention followingin general, the principle of the invention and including such departuresfrom the present disclosure as come within known or customary practicein the art to which the invention pertains, and as may be applied to theessential features hereinbefore set forth, as fall within the scope ofthe invention or the limits of the appended claims.
